Subject: eal: suppress error log on multi-process hotplug
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7bc7bc3516ad7d4c082cb24daedd02117cc162ef;p=dpdk.git

eal: suppress error log on multi-process hotplug

This is a normal case that the primary process already
owned one device while the secondary process try to
attach it, so suppress the error log here to exclude
this case.
